Here are all the images from last night's premiere of Testament of Youth

The premiere of Testament of Youth, possibly the most generation-defining memoir that there is of the First World War, took place last night in Leicester Square – and we’ve got the pictures. The film sees a young Vera Brittain, later an influential pacifist, feminist and writer, as she prepares for Oxford in the dreamlike days before war is declared. Testament of Youth tells her story as she moves from middle class Derbyshire to university to a Camberwell hospital to war-torn France, and eventually back again.Flick through our gallery below to see stars including Alicia Vikander (you might not recognise her name now, but we can guarantee that you’ll know it very well by the end of 2015) and Game of Thrones’ Kit Harington taking to the red carpet.They’re joined by co-stars Taron Egerton and Colin Morgan, as well as Baroness Shirley Williams, the influential politician and Vera Brittain’s daughter.Watch the trailer here:Testament of Youth is released in UK cinemas on 16th January 2015.
